There are four methods of cleaning coal, viz, (i) hand picking, (ii) wet washing, (iii) froth flotation and (iv) dry cleaning. The first method has been the earliest and can be effective under suitable conditions. It is gradually disappearing due to its being expensive, inefficient and strenuous. The dry cleaning method is sometimes used for ...

Coal continues to play a major role in the economic development of India, especially in conventional power generation plants. The wet beneficiation process for coal cleaning is currently the predominant method of purification of coal in the world. However, dry beneficiation of coal has obvious advantages over wet processes.

ash (grade) in a coal seam is assessed through combusting a sample and comparing weights prior and after. The difference is the proportion of non-combustible material (ash) present. Preparation plant yield is therefore very dependent upon (trade-off) washing out the non-combustible materials – ash. Density (washability)

In this study, the works about gravity separation for coal cleaning in the last 10 years were reviewed. It was found that the studies have mainly contributed to the separation of fine coal as well as dry-coal separation, while conventional technologies are more focused on modeling to estimate and control the separation process.
